In Aim High, our shooter was directly driven by the large
CIM motor. The RC measured the speed of the shooting
wheel and adjusted the motor power to tightly regulate
the speed. The desired speed was a function of measured
range to the target goal. The considerations that you
mention, properly doing the physics, were a fundamental
part of the design process. To obtain a fast spin up,
the rotational inertia of the ball shooting
wheel needed to be low. To have the ball shooting wheel
store enough energy that it could shoot the ball and not
stall, the rotational inertia of the ball shooting wheel needed
to be high. When all was said and done, we found the
right compromise for the rotational inertia that provided
a fast spin up and enough energy storage to shoot balls
without losing too much speed.
I would encourage you to pursue your study of physics
so that you develop a proper understanding of these things.
